i would think OSIM is the most premium and reputable one.
perhaps they do good marketing, and brand image.
Welll- get what fits your pocket ba. Other brand also can use- each got its pro and cons. ( like Mercedes vs Myvi)
Itsu- as heard is local brand. previous OGAWA founder sold OGAWA to SG company, and now restarting its own brand.
Now- a few words for consideration - compare to massage outside.
> massage outside definitely give better result, apply more pressure to the sensitive point.
> it is cheaper or more expensive? depends how often you massage ba. if use massage chair daily then definitely cheaper.
> it is convieneint- don't need drive, don't need appointment. can massage when take a nap ( i feel a bit too hot) or when watching TV.
> it is more hygiene.
yes- build in some cost for repair after a few years. there are parts that can subject to wear and tear.
but yes- the result is more for relaxing, and cant give deep massage.
PS: lets continue to keep this topic in the right context.
PS 2: OSIM pannai marketing- got a menu for you pick the type of massage, and match it with music. Best effect is with the eye massager.
I've got an OSIM, going to be around 5 years. i used average twice a week ba. it is wrapped up quite warm, so recommended to put near aircond.
and yes- many people bought already seldom used, end up like exercise bike ( use to keep clothes which are washed, yet to fold/iron)

After much survey, i purchased ULove3 because it has sensor to detect any irregularity within your sprain and apply the method to correct it. Apparently it's one of their patented features. Will update more info later and welcome any questions from Ktards.
